Sanjay Patel 33f83995a8 [CodeGen] fix const-ness of cbrt and fma 
cbrt() is always constant because it can't overflow or underflow. Therefore, it can't set errno.

fma() is not always constant because it can overflow or underflow. Therefore, it can set errno.
But we know that it never sets errno on GNU / MSVC, so make it constant in those environments.

Sanjay Patel 040fbe3027 [CodeGen] split math and complex tests into separate files; NFCI 
The files are already large, and we may need to add even more RUNs to 
distinguish differences based on OS, environment, or other platform things.
